In 2018, Tamaya Peressini, from The Queensland Alliance for Agriculture and Food Innovation (QAAFI), a research institute of the University of Queensland (UQ), travelled to CIMMYT in Mexico as part of her Honours thesis research focused on a disease called tan spot in wheat.

Tan spot is caused by the pathogen Pyrenophora triciti-repentis (Ptr), and her project aimed to evaluate the resistance of tan spot in wheat to global races to this pathogen.

“The germplasm I’m studying for my thesis carries what is known as adult plant resistance (or APR) to tan spot, which has demonstrated to be a durable source of resistance in other wheat pathosystems such as powdery mildew,” said Tamaya.

Symptoms of tan spot on wheat plants

Tan spot is prevalent worldwide, and in Australia causes the most yield loss out of the foliar wheat diseases. In Australia, there is only one identified pathogen race that is prevalent called Ptr Race 1. For Ptr Race 1, the susceptibility gene Tsn1 in wheat is the main factor that results in successful infection in Ptr strains that carry Toxin A. However, globally it is a more difficult problem, as there are seven other pathogen races that consist of different combinations of necrotrophic toxins. Hence, developing cultivars that are multi-race resistant to Ptr presents a significant challenge to breeders as multiple resistant genes would be required for resistance to other pathogens.

“At CIMMYT I evaluated the durability of APR I identified in plant material in Australia by inoculating with a local strain of Ptr and also with a pathogen that shares ToxA: Staganospora nodorum.”

“The benefit of studying this at CIMMYT was that I had access to different strains of the pathogen which carry different virulence factors of disease, I was exposed to international agricultural research, and importantly, I was able to create research collaborations that would allow the APR detected in this population to have the potential to reach developing countries to assist in developing durably resistant wheat cultivars for worldwide deployment,” explained Tamaya.

Recent work in Dr Lee Hickey’s laboratory in Queensland has identified several landraces from the Vavilov wheat collection that exhibited a novel resistance to tan spot known as adult plant resistance (APR). APR has proven to be a durable and broad-spectrum source of resistance in wheat crops; namely with the Lr34 gene which confers resistance to powdery mildew and leaf stem rust of wheat.

“My research is focussed on evaluating this type of resistance and identifying whether it is resistant to multiple pathogen species and other races of Ptr. This is important to the Queensland region, as the northern wheat belt is significantly affected by tan spot disease. Introducing durable resistance genes to varieties in this region would be an effective pre-breeding strategy because it would help develop crop varieties that would have enhanced resistance to tan spot should more strains reach Australia. Furthermore, it may provide durable resistance to other necrotrophic pathogens of wheat,” said Tamaya.

The plant material Tamaya studied in her honours thesis was a recombinant inbred line (RIL) population, with the parental lines being the APR landrace (carries Tsn1) and the susceptible Australian cultivar Banks (also carries Tsn1). To evaluate the durability of resistance in this population to other strains of Ptr, this material along with the parental lines of the population and additional land races from the Vavilov wheat collection were sent to CIMMYT for Tamaya to perform a disease assay.

“At CIMMYT I evaluated the durability of APR identified in plant material in Australia by inoculating with a local strain of Ptr and also with a pathogen that shares ToxA: Staganospora nodorum. After infection, my plant material was kept in 100 per cent humidity for 24 hours (12 hours light and 12 hours dark) and then transferred back to regular glasshouse conditions. At 10 days post infection I evaluated the resistance in the plant material.”

From the evaluation, the APR RIL line demonstrated significant resistance compared to the rest of the Australian plant material against both pathogens. The results are highly promising, as they demonstrate the durability of the APR for both pre-breeding and multi-pathogen resistance breeding. Furthermore, this plant material is now available for experimental purposes at CIMMYT where further trials can validate how durable the resistance is to other necrotrophic pathogens and also be deployed worldwide and be tested against even more strains of Ptr.
“During my visit at CIMMYT I was able to immerse myself in the Spanish language and take part in professional seminars, tours, lab work and field work around the site. A highlight for me was learning to prepare and perform toxin infiltrations for an experiment comparing the virulence of different strains of spot blotch.”

“I also formed valuable friendships and research partnerships from every corner of the globe and had valuable exposure to the important research underway at CIMMT and insight to the issues that are affecting maize and wheat growers globally. Of course, there was also the chance to travel on weekends; where I was able to experience the lively Mexican culture and historical sites – another fantastic highlight to the trip!”

Visiting the Sun and Moon temples of Teotihuacan

“I would like to thank CIMMYT and Dr Pawan Singh for hosting me and giving the opportunity to learn, grow and experience the fantastic research that is performed at CIMMYT and opportunities to experience parts of Mexico. The researchers and lab technicians were all so friendly and accommodating. I would also like to thank my supervisor Dr Lee Hickey for introducing this project collaboration with CIMMYT. Lastly, I would like to thank the Crawford Fund Queensland Committee for funding this visit; not only was I able to immerse myself in world class plant pathology research, I have been given valuable exposure to international agricultural research that will give my research career a boost in the right direction,” concluded Tamaya.

The saving grace of a hefty investment

A man in his early 20s walked the winding roads of Sajiara village, Dumuria upazila, Khulna District in Bangladesh. His head hanging low, he noticed darkness slowly descending and then looked up to see an old farmer wrapping up his own daily activities. With traditional tools in hand, the farmer looked exhausted. The young man, Raju Sarder, considered that there had to be a better way to farm while alleviating his drudgery and that of others in the community.

Determined to act, Raju set out to meet Department of Agricultural Extension (DAE) officials the very next day. They informed him about the Mechanization and Irrigation project of the Cereal Systems Initiative for South Asia (CSISA MI). They also introduced him to the project’s most popular technologies, namely the power tiller operated seeder, reaper and axial flow pumps, all of which reduce labor costs and increase farming efficiency.

Raju found the reaper to be the most interesting and relevant for his work, and contacted CSISA SI to acquire one.

The first challenge he encountered was the cost — $1,970 — which as a small-scale farmer he could not afford. CSISA MI field staff assured him that his ambitions were not nipped in the bud and guided him in obtaining a government subsidy and a loan of $1,070 from TMSS, one of CSISA MI’s micro financing partners. Following operator and maintenance training from CSISA MI, Raju began providing reaping services to local smallholder rice and wheat farmers.

He noticed immediately that he did not have to exert himself as much as before but actually gained time for leisure and his production costs dwindled. Most remarkably, for reaping 24 hectares Raju generated a profit of $1,806; a staggering 15 times greater than what he could obtain using traditional, manual methods and enough to pay back his loan in the first season.

“There was a time when I was unsure whether I would be able to afford my next meal,” said Raju, “but it’s all different now because profits are pouring in thanks to the reaper.”

As a result of the project and farmers’ interest, field labor in Raju’s community is also being transformed. Gone are the days when farmers toiled from dawn to dusk bending and squatting to cut the rice and wheat with rustic sickles. Laborious traditional methods are being replaced by modern and effective mechanization.

Through projects such as CSISA MI, CIMMYT is helping farmers like Raju to become young entrepreneurs with a bright future. Once poor laborers disaffected and treated badly in their own society, these youths now walk with dignity and pride as significant contributors to local economic development.

CSISA MI is a partnership involving the International Maize and Wheat Improvement Center (CIMMYT) and iDE, a non-governmental organization that fosters farmers’ entrepreneurial development, with funding from the USAID mission in Bangladesh under the Feed the Future Initiative.

New publication: Climate change impact and adaptation for wheat protein

Globally, wheat provides around 20 percent of the calories and protein in human diets. By mid-century, crop production must increase by 60 percent to meet global food demand and help reduce hunger, a challenge made even harder by climate change. “Climate Change Impact and Adaptation for Wheat Protein,” a study published in Global Change Biology in September 2018, examines why wheat grain protein concentration — a determinant of grain quality — is often overlooked in relation to improving global crop production in the face of climate change challenges.

“The impact of climate change on crops typically focuses on productivity; however, there are nutritional implications too,” says key contributor to the study Matthew Reynolds, wheat physiologist at the International Maize and Wheat Improvement Center (CIMMYT). “Since wheat also provides a significant proportion of protein in the diets of millions of resource-poor people, the negative impact of increased atmospheric CO2 on protein concentration in the grain is a disturbing fact,” stated Reynolds. “If not addressed, it could have a devastating impact on the health and livelihoods especially of marginalized people who cannot easily afford diverse sources of protein in their diet.”

Multi-location field trials, in addition to model testing, were used to systematically analyze the effects of increasing temperature, heat shocks, elevated atmospheric CO2 concentration, nitrogen, water deficiency and the combination of these factors on yield and wheat grain protein in the world’s main wheat producing regions. This study marked the first time that heat shock and high temperature interaction with elevated CO2 concentration was tested through an impact model. As noted in the study, “This is the most comprehensive study ever done of the effect of climate change on yield and the nutritional quality of one of the three major sources of human food security and nutrition.”

Nearly 3,000 smallholder wheat farmers throughout Pakistan will begin to sow seed of newer, high-yielding, disease-resistant wheat varieties and spread the seed among their peers in 2019, through a dynamic initiative that is revitalizing the contribution of science-based innovation for national agriculture.

Some 73 tons of seed of 15 improved wheat varieties recently went out to farmers in the provinces of Baluchistan, Gilgit Baltistan, Khyber Pakhtunkhwa, Punjab and Sindh, as part of the Agricultural Innovation Program (AIP), an initiative led by the International Maize and Wheat Improvement Center (CIMMYT) with funding from the US Agency for International Development (USAID).

“Our main goal is to help farmers replace outdated, disease-susceptible wheat varieties,” said Muhammad Imtiaz, CIMMYT scientist and country representative for Pakistan who leads the AIP. “Studies have shown that some Pakistan farmers grow the same variety for as long as 10 years, meaning they lose out on the superior qualities of newer varieties and their crops may fall victim to virulent, rapidly evolving wheat diseases.”

With support from CIMMYT and partners, participating farmers will not only enjoy as much as 20 percent higher harvests, but have agreed to produce and share surplus seed with neighbors, thus multiplying the new varieties’ reach and benefits, according to Imtiaz.

He said the new seed is part of AIP’s holistic focus on better cropping systems, including training farmers in improved management practices for wheat.

Wheat is Pakistan’s number-one food crop. Farmers there produce over 25 million tons of wheat each year — nearly as much as the entire annual wheat output of Africa or South America.

Annual per capita wheat consumption in Pakistan averages over 120 kilograms, among the highest in the world and providing over 60 percent of Pakistanis’ daily caloric intake.

The seed distributed includes varieties that offer enhanced levels of grain zinc content. The varieties were developed by CIMMYT in partnership with HarvestPlus, a CGIAR research program to study and deliver biofortified foods.

According to a 2011 nutrition survey, 39 percent of children in Pakistan and 48 percent of pregnant women suffer from zinc deficiency, leading to child stunting rates of more than 40 percent and high infant mortality.

“I am very excited to be part of Zincol-16 seed distribution, because its rich ingredients of nutrition will have a good impact on the health of my family,” said Munsif Ullah, a farmer from Swabi District, Khyber Pakhtunkhwa province.

Other seed distributed includes that of the Pakistan-13 variety for rainfed areas of Punjab, Shahkar-13 for the mountainous Gilgit-Baltistan, Ehsan-16 for rainfed areas in general, and the Umeed-14 and Zardana varieties for Baluchistan.

All varieties feature improved resistance to wheat rust diseases caused by fungi whose strains are mutating and spreading quickly in South Asia.

CIMMYT and partners are training farmers in quality seed production and setting up demonstration plots in farmers’ fields to create awareness about new varieties and production technologies, as well as collecting data to monitor the varieties’ performance.

They are also promoting resource-conserving practices such as balanced applications of fertilizer based on infrared sensor readings, ridge planting, and zero tillage. These innovations can save water, fertilizer, and land preparation costs, not to mention increasing yields.

“CIMMYT’s main focus in Pakistan is work with national wheat researchers to develop and spread better wheat production systems,” Imtiaz explained. “This includes improved farming practices and wheat lines that offer higher yields, disease resistance, and resilience under higher temperatures and dry conditions, as well as good end-use quality.”

CIMMYT’s partners in AIP include the National Rural Support Program (NRSP), the Lok Sanjh Foundation, the Village Friends Organization (VFO), the Aga Khan Rural Support Program (AKRSP), the National Agricultural Research Council (NARC) Wheat Program, the Wheat Research Institute (WRI) Faisalabad and Sakrand centers, AZRI-Umarkot, Kashmala Agro Seed Company, ARI-Quetta, BARDC-Quetta, and Model Farm Services Center, KP.

A wheat self-sufficiency roadmap for Ethiopia’s future

This blog by Jérôme Bousset was originally posted on CIMMYT.org.

The Ethiopian government announced recently that the country should become wheat self-sufficient over the next four years. Why is boosting domestic wheat production important for this country in the Horn of Africa, and could wheat self-sufficiency be attained in the next four years? The Ethiopian Institute for Agricultural Research (EIAR), with the support of International Maize and Wheat Improvement Center (CIMMYT), gathered agriculture and food experts from the government, research and private sectors on November 23, 2018, to draw the first outlines of this new Ethiopian wheat initiative.

The low-tech domestic wheat farming and price support issue

Despite a record harvest of 4.6 million metric tons in 2017, Ethiopia imported 1.5 million tons of wheat the same year, costing US$600 million. Population growth, continuous economic growth and urbanization over the last decade has led to a rapid change in Ethiopian diets, and the wheat sector cannot keep up with the growing demand for pasta, dabo, ambasha and other Ethiopian breads.

The majority of Ethiopia’s 4.2 million wheat farmers cultivate this cereal on an average of 1.2-hectare holdings, with three quarters produced in Arsi, Bale and Shewa regions. Most prepare the land and sow with draft animal power equipment and few inputs, dependent on erratic rainfall without complementary irrigation. Yields have doubled over the last 15 years and reached 2.7 tons per hectare according to the latest agricultural statistics, but are still far from the yield potential.

According to data from the International Food Policy Research Institute (IFPRI), wheat is preferred by wealthier, urban families, who consume 33 percent more wheat than rural households. Ethiopia needs to rethink its wheat price support system, which does not incentivize farmers and benefits mostly the wealthier, urban consumers. Wheat price support subsidies could, for instance, target bakeries located in poor neighborhoods.

Where to start to boost wheat productivity?

Ethiopia, especially in the highlands, has an optimum environment to grow wheat. But to make significant gains, the wheat sector needs to identify what limiting factors to address first. The Wheat initiative, led by Ethiopia’s Agricultural Transformation Agency (ATA), has targeted 2,000 progressive farmers across 41 woredas (districts) between 2013 and 2018, to promote the use of improved and recommended inputs and better cropping techniques within their communities. A recent IFPRI impact study showed a 14 percent yield increase, almost enough to substitute wheat imports if scaled up across the country. It is, however, far from the doubling of yields expected initially. The study shows that innovations like row planting were not widely adopted because of the additional labor required.

Hans Braun, WHEAT CGIAR research program and CIMMYT’s Global Wheat Program director, believes Ethiopian farmers can achieve self-sufficiency if they have the right seeds, the right agronomy and the right policy support.

One priority is to increase support for wheat improvement research to make wheat farmers more resilient to new diseases and climate shocks. Drought and heat tolerance, rust resistance and high yields even in low-fertility soils are some of the factors sought by wheat farmers.

International collaboration in durum wheat breeding is urgently needed as the area under durum wheat is declining in Ethiopia due to climate change, diseases and farmers switching to more productive and resilient bread wheat varieties. Braun advises that Ethiopia set up a shuttle breeding program with CIMMYT in Mexico, as Kenya did for bread wheat, to develop high-yielding and stress-resistant varieties. Such a shuttle breeding program between Ethiopia and Mexico would quickly benefit Ethiopian durum wheat farmers, aiming at raising their yields similar to those of Mexican farmers in the state of Sonora, who harvest more than 7 tons per hectare under irrigation. This would require a policy reform to facilitate the exchange of durum germplasm between Ethiopia and Mexico, as it is not possible at the moment.

Ethiopia also needs to be equipped to respond quickly to emerging pests and diseases. Five years ago, a new stem rust (TKTTF, also called Digalu race) damaged more than 20,000 hectares of wheat in Arsi and Bale, as Digalu — the popular variety used by local farmers — was sensitive to this new strain. The MARPLE portable rust testing lab, a fast and cost-effective rust surveillance system, is now helping Ethiopian plant health authorities quickly identify new rust strains and take preventive actions to stop new outbreaks.

Invest in soil health, mechanization and gender

In addition to better access to improved seeds and recommended inputs, better agronomic practices are needed. Scaling the use of irrigation would certainly increase wheat yields, but experts warn not to dismiss adequate agronomic research — knowing the optimal water needs of the crop for each agroecological zone — and the underlying drainage system. Otherwise, farmers are at risk of losing their soils forever due to an accumulation of salt.

‘’2.5 billion tons of topsoil are lost forever every year due to erosion. A long-term plan to address soil erosion and low soil fertility should be a priority,” highlights Marco Quinones, adviser at ATA. For instance, large-scale lime application can solve the important issue of acid soils, where wheat does not perform well. But it requires several years before the soil can be reclaimed and visible yield effects can be seen.

Mechanization could also boost Ethiopian wheat production and provide youth with new job opportunities. Recent research showed smallholder farmers can benefit from six promising two-wheel tractor (2WT) technologies. Identifying the right business models and setting up adapted training programs and financial support will help the establishment of viable machinery service providers across the country.

Better gender equity will also contribute significantly to Ethiopia becoming self-sufficient in wheat production. Women farmers, especially female-headed households, do not have the same access to trainings, credit, inputs or opportunities to experiment with new techniques or seed varieties because of gender norms. Gender transformative methodologies, like community conversations, can help identify collective ways to address such inequalities, which cost over one percent of GDP every year.

‘’With one third better seeds, one third good agronomy and one third good policies, Ethiopia will be able to be wheat self-sufficient,” concluded Braun. A National Wheat Taskforce led by EIAR will start implementing a roadmap in the coming days, with the first effects expected for the next planting season in early 2019.

The consultative workshop “Wheat Self-Sufficiency in Ethiopia: Challenges and Opportunities” took place in Addis Ababa, Ethiopia, on November 23, 2018.

Global study paves the way for developing gender-transformative interventions

By Dina Najjar

Gender norms – a set of cultural or societal rules or ideas on how each gender should behave – matters deeply on whether people adopt and benefit from innovations. Gender norms are also fluid, as they respond to changes in society, yet many of us fail to catch up with the changing norms.

Example: As farming becomes less and less profitable, men leave rural areas for cities in search of jobs. This leaves women in charge of farms, especially in subsistence farming, but many policymakers mistakenly believe that women’s roles are still confined to the house. This then becomes a barrier for women to benefit equally from agricultural innovations as men do, which negatively affects agricultural production in the household and community, more broadly.

A breakthrough CGIAR global comparative research initiative “GENNOVATE” has paved the way for developing gender-transformative interventions.

Among many resources it offers is a unique, in-depth gender knowledge base, established following five years of painstaking research – undertaken by 11 CGIAR centers, including ICARDA, and gender specialists across the globe. The study’s vast data and analyses have enabled researchers to move beyond smaller, unconnected studies that have largely defined gender research.

In order to address the question of how gender norms influence men, women, and youth to adopt innovation in agriculture and natural resource management, GENNOVATE has engaged 7,500 participants from 137 rural communities in 26 countries in Africa, Asia, and Latin America. The qualitative comparative study employs a framework based on the understanding that for innovation to be effective, women and men on the ground must exercise “agency” and be active participants in adopting new technology or practice.

The findings cast light on hidden norms within rural farming societies, as well as biases that influence decision making, technology access, and adoption within these societies and in rural development programming.

GENNOVATE also provides tools and resources to help the integration of gender sensitivities into agricultural research for development projects. These evidence-based inputs and recommendations can facilitate the development of less-biased, customized interventions that meets the specific needs of target populations. They can also ensure that this is done in an inclusive, responsible manner in tune with local norms.

This means scientists, practitioners, and policymakers can more easily incorporate gender into their work on climate-smart agriculture, conservation agriculture, mechanization, and farmer-training events, just to name a few. In short, it optimizes the chances of adoption of agricultural and environmental innovation.

ICARDA and GENNOVATE

ICARDA has contributed 10 case studies to GENNOVATE. Three case studies from Morocco focused on linking gender norms and agency with innovations in agriculture, such as drip irrigation, and improved wheat and chickpeas varieties. Uzbekistan’s four case studies linked gender norms and agency with improved wheat varieties. Three cases in India’s Rajasthan studied the link of gender norms and agency with improved barley varieties, contract barley farming, and improved goat breeds.

ICARDA also contributed to three of the six studies featured in The Journal of Gender, Agriculture, and Food Security’s special issue dedicated to GENNOVATE.

The paper “What drives capacity to innovate? Insights from women and men small-scale farmers in Africa, Asia, and Latin America” demonstrated that gender norms and personality attributes influence men’s and women’s ability to try out, adopt, and benefit from agricultural innovations, as well as their ability to make decisions around them – this is an area that has been largely underreported in the innovation literature.

“Gendered aspiration and occupations among rural youth in agriculture and beyond” shows that youth and gender issues are inextricably intertwined, and as a result, they cannot be understood in isolation from each other. The study also shows that deeply-ingrained gender norms often dissuade young women from pursuing agriculture-related occupation.

“Community typology framed by normative climate for agricultural innovation, empowerment, and poverty reduction” made a case that inclusive norms can lead to gender equality and agricultural innovation, deepening the capacity to make decisions that can lead to escape from poverty.

ICARDA’s contribution to GENNOVATE has been made possible with support from CGIAR Research Program on Wheat and CGIAR Research Program on Grain Legumes and Dryland Cereals.

IWYP annual report highlights new wheat lines, product development

The International Wheat Yield Partnership (IWYP), a partnership of public sector agencies and private industry focusing on innovations in wheat breeding for significant yield increases, recently released its 2017-2018 Annual Report.  Many new research discoveries have been recorded over the last year, from germplasm with traits to improve genetic yield potential to molecular genetic markers associated with a target trait and new methods and technology to improve screening of individual wheat lines.

Accomplishments include making wheat lines with higher biomass and grain yields available for release in national programs, validating the hypothesis that combining parents with high biomass and good harvest index can boost genetic gains.  IWYP researchers have also made publicly available new wheat lines with increased grain size and spike morphology, which several breeding companies in the UK, Europe and Brazil have requested. Yield trials have also led to the discovery of several physiological trait lines that outperform the best local and International Maize and Wheat Improvement Center (CIMMYT) check varieties in over 27 environments.

The Partnership, which includes 30 projects in more than 50 laboratories in 12 countries, is now in its third year. Outputs from its earliest projects are currently being validated and integrated in a prebreeding pipeline at the IWYP Hub at CIMMYT for development into pre-products. This ensures the best “toolbox” of new traits, genetics, and technology to reach its critical challenge of raising genetic wheat yield potential 50 percent by 2035.

Borlaug 100 wheat in Australia

In a quest for high-yielding wheat to use in the feedlot sector, growers in Queensland, Australia, have released the variety Borlaug 100, developed by breeders at the International Maize and Wheat Improvement Center (CIMMYT). “The fact that the variety has been released in other countries, and that its excellence is contributing as parental material for crosses in many, many other countries, is further proof of our global contribution to multiple stakeholders and farmers,” says Thomas Payne, Head of Wheat Genetic Resources and the Wheat Germplasm Bank at CIMMYT. The Australian growers, who are also the founders of Rebel Seeds, sought to grow wheat without protein requirements to sell to feedlots, a void that needed filling in Australia at the time of the company’s founding in 2015. Since being brought to the country shortly afterwards via the CIMMYT-Australia-ICARDA-Germplasm Evaluation (CAIGE) project as a solution to this problem, Borlaug 100 is now set to be commercially released by Rebel Seeds into the niche feedlot market. Grown as milling wheat in Mexico, Borlaug 100 is thought to be a suitable replacement for the wheat currently marketed by Rebel Seeds as a source of feed grain for livestock. As a result, Borlaug 100 will make its debut in Australia’s National Variety Trials Guide in 2019. Richard Trethowan, a former CIMMYT wheat breeder and now a professor at the University of Sydney, consulted Rebel Seeds throughout their acquisition of Borlaug 100.

Inspiring millennials to focus on food security: The power of mentorship

by Mike Listman, November 13, 2018

As part of their education, students worldwide learn about the formidable challenges their generation faces, including food shortages, climate change, and degrading soil health. Mentors and educators can either overwhelm them with reality or motivate them by real stories and showing them that they have a role to play. Every year the World Food Prize lives out the latter by introducing high school students to global food issues at the annual Borlaug Dialogue, giving them an opportunity to interact with “change agents” who address food security issues. The World Food Prize offers some students an opportunity to intern at an international research center through the Borlaug-Ruan International Internship program.

Plant Microbiologist Tessa Mahmoudi, a 2012 World Food Prize’s Borlaug-Ruan summer intern, says her experience working with CIMMYT researchers in Turkey when she was 16 years old profoundly changed her career and her life.

“For a summer I was welcomed to Turkey not as a child, but as a scientist,” says Mahmoudi, who grew up on a farm in southeast Minnesota, USA. “My hosts, Dr. Abdelfattah A. Dababat and Dr. Gül Erginbas-Orakci, who study soil-borne pathogens and the impact those organisms have on food supplies, showed me their challenges and, most importantly, their dedication.”

Mahmoudi explains she still finds the statistics regarding the global food insecurity to be daunting but saw CIMMYT researchers making real progress. “This helped me realize that I had a role to play and an opportunity to make positive impact.”

Among other things, Mahmoudi learned what it meant to be a plant pathologist and the value of that work. “I began to ask scientific questions that mattered,” she says. “And I went back home motivated to study — not just to get good grades, but to solve real problems.”

She says her outlook on the world dramatically broadened. “I realized we all live in unique realities, sheltered by climatic conditions that strongly influence our world views.”

According to Mahmoudi, her internship at CIMMYT empowered her to get out of her comfort zone and get involved in food security issues. She joined the “hunger fighters” at the University of Minnesota while pursuing a bachelor’s in Plant Science. “I was the president of the Project Food Security Club which focuses on bring awareness of global hunger issues and encouraging involvement in solutions.” She also did research on stem rust under Matthew Rouse, winner of the World Food Prize 2018  Norman Borlaug Award for Field Research and Application.

Pursuing a master’s in plant pathology at Texas A&M University under the supervision of Betsy Pierson, she studied the effects of plant-microbe interactions on drought tolerance and, specifically, how plant-microbe symbiosis influences root architecture and wheat’s ability to recover after suffering water stress.

Mahmoudi incorporates interactive learning activities in her class (see her website, https://reachingroots.org/). Her vision is to increase access to plant science education and encourage innovation in agriculture.Currently, Mahmoudi is involved in international development and teaching. As a horticulture lecturer at Blinn College in Texas, she engages students in the innovative use of plants to improve food security and global health.

“As a teacher and mentor, I am committed to helping students broaden their exposure to real problems because I know how much that influenced me,” Mahmoudi says. “Our world has many challenges, but great teams and projects are making progress, such as the work by CIMMYT teams around the world. We all have a role to play and an idea that we can make a reality to improve global health.”

As an example, Mahmoudi is working with the non-profit Clean Challenge on a project to improve the waste system in Haiti. The initiative links with local teams in Haiti to develop a holistic system for handling trash, including composting organic waste to empower small holder farmers to improve their soil health and food security.

“Without my mentors, I would not have had the opportunity to be involved in these high impact initiatives. Wherever you are in your career make sure you are being mentored and also mentoring. I highly encourage students to find mentors and get involved in today’s greatest challenge, increasing food security.”

In addition to thanking the CIMMYT scientists who inspired her, Mahmoudi is deeply grateful for those who made her summer internship possible. “This would include the World Food Prize Foundation and especially Lisa Fleming, Ambassador Kenneth M. Quinn, the Ruan Family,” she says. “Your commitment to this high-impact, experiential learning opportunity has had lasting impact on my life.”
